Letters Patent No. 66,408, dated July 2, 1867.

IMPROVED BRICK-Manama TO ALL WHOM IT MAY CONCERN:

Be it known that I, A. J. SPRAGUE, of Toledo, in the county of Lucas, and State of Ohio, have invented a new and improvedtMachine for Moulding and PressingBricks, and that the following description, taken in connection with .the accompanying drawings hereinafter referred to, forms a full and exactspecification of the same, wherein I have set forth the nature and principles of mysaid improvements, by which my invention may be distinguished fromall others of a similar class, together with such parts as I claim, and desire to have secured to me by Letters Patent. 7

This invention relates to a new and improved machine for moulding and pressing bricks, and it consists in a novel means for pressing the clay into the moulds, with a feeding and discharging device, and a guard-grating,

as hereinafter set forth, wherehy clay may be moulded and pressed .iuto proper form very expeditiously and in a. perfechmanner. In the accompanying sheets of drawings Figure 1 Sheet No. 1, is a-front elevation of my invention.

.Figure 2, a vertical section of the same taken in the line mix, fig. 1.

Figure 3, SheetNo. 2,.a horizontal section of the same takenin the-line yy, fig. 2.

Figure 4, ahorizont alsection ofthe press-box taken in the'li'ne z e, iig Q.

Similar letters of reference indicate like parts.

represents a frame of rectangular form, and constructed in any proper manner to support the working parts. In the upperwpartof this frame A the mud-mill B isplaced, the sidesfof the case of which aresecured in the frame. This mudmill, as usual, is provided with a'vertical central shaft, 0, having horizontal armsD extending therefi-omtepulveriz and temper the clay, and the bottornf'a of the mud-mill has. a rectangular opening, 6, made in .it, over which. the tempered clay passes into the press-box F. This press-box F contains the Presser G, which .is composed ofua curved .arm or blade extending from a shaft, H, which passes horizontally through the press-box Frand has a bevel-wheel, I, on one end of it into which a bevel-wheel, J, on the lower endof; a shaft, =K, gears, the latter having its bearings at one-side of the frame A. On the upperend of-the shaft K there is'secured a bevel-pinion, L, into which a bevel-pinion, M, gears, the latter beingon :a horizontal shaft, N, from which the mud-Inill shaft C isdriven by bevel-gears O. In thebottom of the press-box F there is'fitted aigrating, P, through which the tempered clay is forced into the mould-box Q. The presser G rotates inthe direction indicated-by the arrows in fig. 2, and the mould-box Q when receiving the clay nests upon rollers R in a pivoted frame, S,;underneath the press-box, saidfra-me being pivoted at its rear end, assho'wn. at a, and having its front cudresting on eccentrics d d on'a shaft, T, shown in figs. 1 and 2. The grating E prevents stones and other large foreign substances from entering thepress-box. The mould-boxes are fed underneath the press-box and out from underneath the same by means. of aplate, U, which is attached by a set-screw, e, .to

.3 cross-bar, V,which is secured to two bars W W, the latter resting on rollers X in the frame A'. These bars W' Wdiave each auupright, Y, secured to them, against which arms Z Z on the shaft H come in contact and .Inovethe bars W W, and consequently the 'plate Uforward, the latter shoving the mould-box underneath the press-box, theplatc Uand bars W W being drawn-back by aspriug, A, or its equivalent. The empty mouldboxes are 'placed on a stationaryiplat, B, just back of the press-box and over which the plate U works.

Having thus described my invention, Iclaim as new, and desire to securezby Letters Patent- 1. The rotary presser G, arranged within the-pres's-box F, to operate-inthe manner substantially as and for theipurpose .set forth.

2. The grating E placed over the opening 6, inrthe bottom ofthemud-mill B, substantially as and for the purpose specified.

3, Operating the mould-feeding plate U through themediumof the revolving arms Z Z, on the shaft H, the uprights-Y onl-the bars W W, and the spring A or its equivalent, all arranged-substantially as shown and described.

The above specification of my invention signedbyme thisl20th'day of March,-1867. I
